VitroGLO-TPGC-DI
Low NOx Throughport Gas Burner
The VitroGLO-TPGC-DI water cooled burners are designed to be inserted into the port neck of a regenerative glass furnace. The burners are fitted to the Global Combustion Systems retraction mechanism, which is used to withdraw the burner from the port when not firing. The use of the VitroGLO-TPGC-DI throughport burners with the retraction mechanism provides stable reproducible combustion conditions, essential for high glass quality.
The VitroGLO-TPGC-DI burner combines Global Combustion’s highly successful Low NOx dual impulse flame technology and the throughport gas burner technology, producing a high luminous adjustable flame ideally located withing the combustion air stream. The flame length is adjustable (by up to 30%) by means of proportioning the velocities of the two concentric gas jets. This is controlled within the burner by adjusting a calibrated dial on the back of the burner.
The single conical flame configuration allows for one, two, three or four burners to be installed on each port. This burner is interchangeable with Global Combustion’s Throughport Oil Burner (VitroOIL-TP).
The retraction mechanism operates pneumatically, and is designed for a long low maintenance life and ensures perfect alignment without the need for adjustment during operation. Vertical angle, horizontal and vertical position adjustments are incorporated into the mechanism. single mechanism can carry up to four burners per port.
Global Combustion Systems can also provide auxiliary equipment including a complete natural control system, with full supervision and commissioning services.
